sql_gen.py: EnsureNotNull: Take a type param instead of a null param so that the EnsureNotNull object stores the underlying column's type

sql_gen.py: underlying_col(): Support non-Col inputs

sql_gen.py: EnsureNotNull: Removed default value for null param to remind user that default value depends on value's type and will not always be a string

sql.py: add_index(): Added ensure_not_null param to disable the ensure_not_null functionality to force a plain index

sql.py: flatten(): Add indexes on the created table so its columns can be used in an O(n) merge join

sql_gen.py: null_sentinels: Added value for integer type

sql_gen.py: CompareCond.to_str(): Always wrap the left-side column if it's nullable. Wrap the right-side value if the left side was wrapped, rather than if both the left and right side are nullable. This causes coalesce() indexes to be used to look up NULL values using the value NULL gets coalesced to, rather than doing a sequential scan.

sql_gen.py: Run truncate() on all identifiers so that literal-string-based lookups for an identifier (such as in db.col_info()) don't use the untruncated value

sql_gen.py: Added truncate()

sql.py: put_table(): Resolving default value column: Fixed bug where default value of None was used as a key for mapping, even though this is an invalid Col name

sql_gen.py: ensure_not_null(): If input column cannot be ensured to be NULL, pass any raised exception through rather than suppressing it and leaving the column in a nullable state

schemas/functions.sql: _merge: Changed indexes to use `COALESCE` to match what sql_gen now does

schemas/functions.sql: _alt: Changed indexes to use `COALESCE` to match what sql_gen now does

sql_gen.py: CompareCond.to_str(): Handle nullable columns using ensure_not_null()

sql_gen.py: ensure_not_null(): Raise NoUnderlyingTableException if can't ensure not null for that reason

sql_gen.py: is_underlying_table(): Support non-Table inputs

sql_gen.py: NamedValues: Call set_cols_table() with the created table, not just the name, so that is_underlying_table() works properly

sql_gen.py: underlying_col(): If no underlying table, raise NoUnderlyingTableException

sql_gen.py: Added is_underlying_table()

sql_gen.py: ensure_not_null(): Call underlying_col() on the column to remove all renamings

sql_gen.py: ensure_not_null(): Added ignore_unknown_type param

sql_gen.py: CompareCond.to_str(): Put handling nullable columns as a separate step so it can be expanded

csv2db: Errors table: Removed no longer needed sql_gen.EnsureNotNull() because this is now added automatically

sql.py: add_index(): Handle nullable columns by using sql_gen.ensure_not_null() to automatically add a coalesce() wrapper where needed

sql_gen.py: Added ensure_not_null()

sql.py: DbConn.col_info(): Fixed bug where is_nullable needed to be cast to a boolean

sql.py: cast(): Support string column name inputs

sql.py: DbConn: Renamed col_default() to col_info() and have it return a sql_gen.TypedCol object containing all the TypedCol info about the column, not just the default value

sql_gen.py: TypedCol: Added default and nullable params

dicts.py: Import util after items that util depends on have been defined, to avoid unsatisfied circular dependency

sql.py: DbConn.col_default(): Pass the connection to sql_gen.as_Code() so it fixes the syntax on values returned by PostgreSQL

sql_gen.py: as_Code(): Added optional db param, which causes the function to run db.std_code() on the value to fix the syntax

sql.py: DbConn: Added std_code()

db_xml.py: Removed into_table_name() because this functionality is now handled by sql.into_table_name()

sql.py: into_table_name(): Also parse hierarchical tables (mappings with a rank column) using a special syntax

sql.py: put_table(): Fixed bug where distinct_on included columns that were not in the input table, and were thus incorrectly taken from the LEFT JOINed output table

sql.py: track_data_error(): Do nothing if cols are empty, because mk_track_data_error() requires at least one col. mk_track_data_error(): Assert that cols are not empty because VALUES clause requires at least one row.

bin/map: by_col: Pass on_error to db_xml.put_table() that calls ex_tracker.track()

sql.py: put_table(): No handler for exception: Pass exception to on_error() instead of raising a warning, so that error message can be formatted

db_xml.py: put_table(): Pass on_error to sql.put_table()

db_xml.py: put_table(): Take on_error param like row-based put()

sql.py: put_table(): Take on_error param

sql.py: get_cur_query(): Removed no longer used input_params parameter

sql.py: Removed unused mogrify()

sql.py: DbConn.DbCursor.execute(): Removed no longer used params parameter

sql.py: with_autocommit(): Use isolation_level attr and set_isolation_level() method of connection instead of autocommit attr to support older versions of psycopg2

sql.py: DbConn.DbCursor.execute(): Only fetch all rows for empty SELECT query, to support older versions of Python that would give a "no results to fetch" error for other types of queries

csv2db: When reraising exception, use `raise` instead of `raise e` to preserve whole stack trace

sql.py: Removed no longer used _query_lookup()

sql.py: DbConn: Cache queries without params, as params are no longer used

sql.py: DbConn.is_cached(): Removed no longer used params parameter

sql.py: Removed no longer used run_raw_query()

sql.py: run_query(): Call db.run_query() directly instead of via run_raw_query()

sql.py: DbConn.run_query(): Removed no longer used params parameter

sql.py: DbConn._db(): Setting search_path: Use esc_value() instead of params

sql.py: run_query(): Removed no longer used params parameter

sql.py: run_query_into(): Moved main case (into != None) outside of if statement because the special-case if statement contains `return`

sql.py: run_query_into(): Removed no longer used params parameter

sql.py: mk_insert_select(): Removed no longer used params parameter

sql.py: mk_insert_select(): Return just the query instead of the query plus empty params

sql.py: mk_select(): Return just the query instead of the query plus empty params

sql.py: tables(): Use select() instead of a custom run_query() to avoid using params, which will be deprecated to make it easier to support old versions of Python

sql.py: DbConn.DbCursor.execute(): Require that params are empty, to ensure that code uses db.esc_value() instead. This keeps literal values in the same place as the rest of the query, so that they do not need to be maintained and passed around separately in a params list.

sql.py: constraint_cols(): Use db.esc_value() instead of params

sql.py: index_cols(): Use db.esc_value() instead of params

sql.py: add_pkey(): Use simpler `ADD PRIMARY KEY` syntax to avoid having to create a name for the primary key

schemas/postgresql.nimoy.conf: shared_buffers: Fixed syntax error where decimals were not supported

sql.py: truncate(): Re-added support for string tables using sql_gen.as_Table(). This fixes empty_db(), which relied on this functionality.

sql_gen.py: as_Table(): Added schema param to use as default schema

inputs/SALVIAS: Switched to using CSV exports of the DB, so that staging tables could be created for column-based import

sql.py: run_query_into(): Added add_indexes_ param which causes the function to add indexes on the created table

sql.py: create_table(): Use new add_indexes()

sql.py: Added add_indexes()

sql.py: get_cur_query(): Fixed bug where strings.ustr() needed to be used instead of str() when ensuring that get_cur_query() returns a string

sql.py: cast(): Removed conditional checks for save_errors, since it's now always true if the function got passed the `not save_errors` special case

sql.py: cast(): Only convert errors to warnings if errors will be saved in errors_table, so that import will always be aborted if user supplied invalid values in the mappings, even if these values are passed through a relational function

sql.py: put_table(): Support inserting tables with all default values, by providing the pkey's default value for all rows so that the SELECT query has at least one column

sql_gen.py: is_table_col(): Check that input is a Col object

sql.py: put_table(): Assert that mapping is non-empty

sql.py: mk_select(): Assert that fields list is non-empty

sql.py: DbConn.DbCursor.execute(): Set _is_insert only if query starts with INSERT, so that function definitions containing INSERT are not cached as INSERT statements (exceptions only) themselves

sql.py: DbConn.DbCursor.execute(): Fixed bug where params == None would apparently turn off the mogrifier completely, causing "%"s to be excessively escaped, by just setting params to None if it was [] or () and not using strings.esc_for_mogrify() at all

sql.py: DbConn.DbCursor.execute(): If not using params, escape the query using strings.esc_for_mogrify() in case any literals contained "%"s

strings.py: Added esc_for_mogrify()

sql.py: create_table(): Add indexes on all non-pkey columns, unless turned off or deferred using new param col_indexes

csv2db: Add column indexes on errors table. Use typed_cols and `.to_Col()` to iterate over columns to add indexes on, for the main and errors tables.

sql.py: Added track_data_error(). put_table(): ignore(): Take extra e param for the exception. Use track_data_error() to store the invalid value in the errors table.

sql_gen.py: Join.to_str(): Add newline before and after right table if it's been renamed (and therefore takes up multiple lines)

exc.py: ExceptionWithCause: Store the cause in an instance variable for later use

sql.py: mk_track_data_error(): Rename the errors_table to make the generated SQL less verbose

sql.py: mk_insert_select(): Run sql_gen.remove_table_rename() on table to get just the actual name in the DB

sql_gen.py: Added remove_table_rename()

sql_gen.py: Col: Run `.to_Table()` on table to get just the reference to the table, not any SQL code that defines it

sql.py: Added mk_track_data_error() and use it in cast(). This also ensures that if only one source column's row in the CROSS JOIN violates a unique constraint, other source columns' rows are still inserted.
